Specication of Letters Eatent.

.Patented May 29, 1917.

Application led October 19, 1915. Serial No. 56,792.

To all Lv/wm t may concern:

Be it known that I, CHARLES METZLER, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Dental-V VVaste Receivers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this speciication.

My invention relates to dental waste receivers, particularly to such as are designed Y said waste receiver.

Fig. 3 is a top view of my invention.

The numeral l indicates a cylindrical casing or cup. The said casing has on one side bosses 2 for the attachment of a bracket 3 by means of screws tas shown in Fig. 1 of the drawings. The bracket 3 has a horizontal stem 4a which is designed to be inserted in the slot of a holder 5 which is secured to the dental stand or other suitable xture. The casing l has at its top a round opening 6 and is provided with a pivotal cover 7 for said opening. The lower end of said casing is open and the lower edge is provided with bayonet slots 8 for the'purpose hereinafter set forth. Adapted to iit inside of the casing 1 is a cylindricalv cup 9, the upper end of which is open. The bot- Y tom of saidvcup has a handle 10. On oppo-` site sides of the cup and near-the bottomv thereof, are studs 11 adapted to fit into and be secured by the bayonet slots 8 as shown in Fig. l.

The nature and operation of my inven-v tion will be readily apparent to those skilled in the art to which the same appertains from the foregoing description. Thecasing lbeing secured in the holder 5 so that the opening extends downwardly, the cup inserted therein, the studs l1 fitting in the bayonet slots 8 of the casing. A slight rotation of the cup secures the same in the casing. When thus secured, the cup is in position to receive dental waste, as for instance cotton, through the opening 6 in the top of the casing 1, the cover 7 being arranged normally to keep said opening closed. The

9 maybe handle 10 on the bottom of the cup furnishes a convenientY mode for handling the same in its insertion or removal from the casing 1.A

Having thus described my invention, what I claim as new anddesire ters Patent is:

to. secure 4by Let- A dental waste receiver comprising a cylindrical casing, a cup arranged to vfit into said casing, studs near the bottom of said cup, bayonet slots in the bottom end of said cup arranged to receive said studs for temporarily securing said cup in said casing,

an opening in the top of said casing over saldA cup for the insertion or removal of dental waste and aVv cover in said openingv pivotally mounted onsaid casing. Y
